IMPROVEMENT IN WAGON-IRONS.

, The Schedule referred to in these Letters Patent and making part ofthe same.

To all wliom. it may concern Be it knownjthat I, Hnxm' .U.Koounxsrniuinn, of the town of Thornville, in the county of lerry andState of Ohio, have invented certain Improvements in \Vagon-Irous; saidimprovements relating to the ing had to the accompanying drawing makinga part of this specification, in which- Figure l is a view of the tongueof a wagon with the neck-yoke, double-tree, and single or whifiietree;

Figure 2, tongue, clcvis, and bracket;

Figures 3 and 4,'details oi breast-strap ring; 7

Figures 5 and (3, details of neck vokc ring and swivels;

Figures 7 and 8, details of single-tree hook;

Figures 9 and 10, details of double tree and singletree clevises;

Figure 11, double-tree plate;

Figures 12 and 13, details of lnunnicr-strap lnz-wket: and

Figures 14 and 15, details of hammer-strap.

My invention consists in making the irons described by casting them ofmalleable iron instead of forging them, and in so distributing theinetal as to obtain the largest wearing-surfaces where required, and thegreatest strength with the least expenditure of metal, producing moreperfect rings, hooks, cleviscs, &c., than can be forged, and at lesscost.

To enable others skilled in the art to make and use rnyinvention, I willproccedto describe the same.

A is the wagon-tongue.

15, neck-yoke.

(l, double-tree.

I) 1), single-trees or whiliieirecs.

l) is the tonguc-clevis, shown in section in tig. .2.

The plate of this clevis is long, and extends back some distance alongthe tongue, to which it is secured by bolts, screws, or rivets. It isslightly curved to conform to the rounded tongue; at the end where itturns over the metal is thickened, as shown at (I, iig. 2, making astrong clevis. After the turn the metal again flattens out, forming aplate on the lower side oi the tongue.

The bracket h, which prevents the neck-yoke ring from slipping back,passes through the lower side 01' the plate, its shoulder resting on theplate, through the tongue and upper part oi the plate, where it isriveted, joining the plate, bracket, and tongue firmly together. Thetail of the bracket is secured by a screwor bolt.

The wem-ingsnrliroo ol' the bracket, which is at c, very heavy, whilethe remainder of the casting is light.

The neck-yoke ring is of wrought-iron. It is secured to the neck-yoke bythe swivels (I, which are cast.

The link l in'the swivel is thickened at the lower end where thelargering rests.

The head of the ring-bolt a is very stron The plates f and f tit onopposite sides of the yoke,

andare drawn closely to it by the riug-bolt-s, which pass through them,as shown in fig. 5.

The plates are thickened at the bolt holes. The holes in' the lowerplate are slightly slotted, that the rings may be drawn in slightly.

The breast-strap rings are of the shapeshown iu figs, 3 and 4. They aremuoh lighter on the sides than at the upper end, where they hang on thebreaststrap or chain and are subject to wear.

They are cast in the head of the bolt h, a slight shoulder being left oneach side of the head of the bolt, as shown in fi 4.

A wood-screw is out; 011 the bolt h, as shown in fi ii, or aratchet-nail is used in place of the bolt, as shown in fig. 4, the teethon the nail preventing its pulling out. 7

The ferrule i, ornamented and strengthened by a bead, fits over the endof the yoke and prevents its splitting.

The double-tree plate 15, figs. L and 11, is cast of the shape shown. Itrests on the top of the doubletrec, and is secured to itwith screws andbolts.

Two lugs, l; k, turn down over the frontedge of the double-tree,strengthening it, and at the same time affording an iron surface for the'whifllctrec to strike against, and preventing it from marring the woodof the double-tree.

The pin which secures the double-tree to the tongue passcsthrough thehole Zin the plate.

The hamn'icr-strap F, figs; 1, 14, and 15, fits over the thimble l onthe plate E. This strap is a light casting, as shown by the section fig.15, heaviest at vthe lower end where the bracket G passes through it.

This bracket, shown in figs. l2 and 13, is fastened to the tongue byscrews, as shown. The hammer-strap relieves the pin, which secures thedouble-tree from much strain. g

The double-tree clcvis, .l-l', iig. 1, shown by itself, iig. t), is castin one piece. its shape is clearly shown in the drawing.

The clevis slips over the end of the double-tree, to

which it issceurcd by the bolts N N and the long bolt N. This boltpasses through the lug M at the back of the clcvis, and through the woodof the double-tree, preventing the wood from split-tin".

The front end of the clevis, to which the whittletrec is attached, ismade very heavy, as is also the back end, to which the stay-chain isfastened, this arrange- "ment saving the expense of an extra elevis forthe stayrchain.

The whittletreoelevis O, figs. 1 and 10, is east with a heavy wcarin-surfirce, r, where it draws against the double-tree olevis, andshoulders S S, which rest .on the plate t. This plate and the plate tare thickened, as shown, to support the shoulders of the clevis on theone side, and the nuts on the other.

The trace-hooks I, figs. 1, 7, and 8, are cast very light, thickened atthe turn of the hook where the x trace-chain wears, and strengthened bythe thin metal gland or fin It. p

The hook is secured to the end of the whifliletree by the th'iinble r,on which it turns. The washer-o is first driven onto the end of thewhifiietree. This lias. been turned down to fit the thimble, which isfitted on, as shown in fig. 7 the whole being then secured either with aratchet-nail driven into the end of the whiffletree, or by a long woodscrew-bolt, forming a strong, neat finish to the end of the'whiffletree.

Claims What I claim as my invention, and desire to secure byLettersPatent of the United States, is

1. The tongue-elevis E, in combination with the bracket 1), when thelatter is provided with the pin 1), which passes through the lowerbranch. of the clevis and through the tongue, and is riveted at itsupper '3. The double-tree'olevis H, provided with the lug" M, andcombined with the pin N, in the manner set forth,

et. The hook l, in combination with the washer 1- and flanged thimble e,in the manner explained;
